A battery storage facility with a capacity of 282 MWh and an output of 137 MW is currently being built in Lower Saxony. Baywa Re is to take over the operational management for eight years.
The Munich-based renewables subsidiary Baywa Re has secured the contract for the operational management of the Alfeld battery storage project in Lower Saxony. The client is the Danish investment fund Scale Fund. According to Baywa Re, the contract runs for eight years.
According to those involved, the project in Alfeld near Hildesheim (Lower Saxony) is set to become Germany's largest battery storage system to date. The plant will have an output of 137 MW and a storage capacity of 282 MWh. Construction is already underway. The project partners are planning commercial commissioning for the beginning of the third quarter of this year.
According to the company, the storage facility will primarily provide primary control power. For Baywa Re, the project is a further step in the large battery storage business. To date, the company has mainly operated storage systems within so-called hybrid projects. Baywa Re combined battery storage systems with solar or wind parks. Alfeld, on the other hand, is being developed as an independent large-scale storage project without a direct link to a generation park.
Baywa Re relies on digital analysis and control systems to operate the storage facility. The company is working together with Munich-based software provider Twaice, among others. Baywa Re was awarded the contract following a tender process with several competitors.
The market for large battery storage systems is currently growing significantly. This is due to the increasing proportion of renewable energies in the electricity system. Grid operators and energy companies increasingly require flexible systems that can absorb or feed in electricity at short notice. Large stand-alone storage systems are seen as an important component for grid stability and security of supply.
